# German Wiktionary SQLite Database

This is a normalized SQLite database version of the German Wiktionary data.

## Source

Original data from: [cstr/de-wiktionary-extracted](https://huggingface.co/datasets/cstr/de-wiktionary-extracted)

## Database Schema

The database is normalized into the following tables:

- **entries**: Main word entries (word, pos, lang, etc.)
- **senses**: Word definitions and meanings
- **translations**: Translations to other languages
- **sounds**: Pronunciation information
- **synonyms**: Synonymous words
- **tags**: Tags/labels (many-to-many via entry_tags)
- **categories**: Categories (many-to-many via entry_categories)
- **forms**: Word forms (inflections, conjugations)
- **hyphenations**: Hyphenation patterns

## Indexes

Optimized indexes on:
- word (for fast lookups)
- language
- part of speech
- all foreign keys

## Usage

```python
import sqlite3
from huggingface_hub import hf_hub_download

# Download the database
db_path = hf_hub_download(repo_id="cstr/de-wiktionary-sqlite", filename="de_wiktionary.db", repo_type="dataset")

# Query it
conn = sqlite3.connect(db_path)
cursor = conn.cursor()

# Example: Find all entries for "schnell"
cursor.execute('''
    SELECT e.word, e.pos, e.lang, s.sense_data 
    FROM entries e
    LEFT JOIN senses s ON e.id = s.entry_id
    WHERE e.word = ?
''', ('schnell',))

for row in cursor.fetchall():
    print(row)

conn.close()
```
